The result should be confirmed by two consecutive tests done at least 4 weeks apart. absence of clonal lymphocytes in the peripheral blood absence of significant lymphadenopathy (e.g. lymph nodes greater than 1,5 cm in diameter) absence of hepatomegaly or splenomegaly absence of constitutional symptoms Response must persist for a minimum duration of four weeks: Bone marrow with 5 percent myeloblasts with normal maturation of all cell lines. Dysplastic changes may be seen, but should be considered within the normal range of dysplastic changes. Peripheral blood demonstrates hemoglobin 11 g/dl, platelets 100 x 109/L, neutrophils 1 x 109/L, and no circulating blasts. CR unconfirmed

2 Disease status or response to treatment AML ALL CML CLL MDS or MD/MPN or acute leukaemia secondary to previous treatment of another disease First partial remission (PR1) Very good PR (VGPR) Partial remission or response Note: The specification (>1, never CR, Solid tum only) only applies to disease status in Solid Tumours For any other diagnosis, the disease status of PR can have been preceded by a relapsed CR Minimal respponse / Poor partial remission or response At leat one of the following: A decrease in the number of blood lymphocytes by below 50% or more from the value prior to therapy; A decrease in lymph node size by below 50% or more in the sum products of up to 6 lymph nodes, or in one lymph node diameter if only a single lymph node was present prior to therapy, without increase in any lymph node, and no new enlarged lymph node; A decrease in the size of the liver and/or spleen by 50% or more as defined by CT scan, palpation, or ultrasound. The blood count should show one of the following results if abnormal prior to therapy:. Polymorphonuclear leukocytes at 1.500/μL or more or 50% improvement over baseline without G-CSF support;. platelet counts greater than /μL or 50% improvement Response / improvement (no CR) Relapse > 5% blasts in the bone marrow after a period of Complete remission. If unqualified, Relapse is considered to be Haematological relapse At least one Complete remission was achieved with a previous treatment but the patient has relapsed since then Haematological Relapse > 5% blasts in the bone marrow after a period of Complete remission. Cytological and/or histological evidence of the disease in the marrow-blood and/or in extramedullary sites (CNS, testis, skin, etc.) in a patient considered to have been in Haematological complete remission Cytogenetic Relapse Reappearance of chromosome anomalies detected earlier in the history of the disease. Cytogenetic relapse can only be determined if Cytogenetic remission has been previously demonstrated. Presence of one or more t(9:22) positive metaphases with standard cytogenetics or hypermetaphase FISH and/or >2% cells with the BCR/ABL fusion gene by interphase FISH, in a patient lacking any evidence of the disease at haematological/clinical level.
